**IF
YOU LIKE ALEKS, BUT YOU FIND THE PACE IN 141 TO BE TOO FAST, TRY THE MATH 15s!**

These are great, 1-unit, online, ALEKS-based,
self-paced refreshers that have helped many students. 15E is trig; 15F is
college algebra. A No-Pass grade does not affect GPA, though it does appear on
your transcript; it can be a problem if you are on academic probation. 15E
includes 15D (geometry). Instead of enrolling in both 15E and 15F, contact the
instructor, and they may be able to make arrangements with you to just enroll
in one Precalculus class, though you may be facing material you have not seen
yet.

These are offered at different times throughout the
semester. You could take more than one in one semester! Get a good foundation
for your classes!

*Printing Suggestions for Typed Files*

I recommend two-page-to-a-side and/or double-sided printing to
save paper. Color printing is nice, but B&W printing is cheaper.

These
are pdf files. You can get the free Adobe Reader at http://www.adobe.com. Get a version that is
compatible with your system!

*Class Notes*

Many
students benefit from **printing the notes** for a lecture beforehand, **reviewing**
them, and **commenting** on them in class.

You
may want to take personalized sketch notes in class.

Corrections: (0:48-1:07) The
double-nappe cone (or simply cone here should not be thought of as finite, so
there are no bases nd there is no base perimeter. The term directrix
is used elsewhere, especially when describing parabolas.

In
previous semesters, the final was cumulative. For your information, here was
